Ten,

There are two things that help Coppermine edge out Athlon in performance: on-die cache, and RDRAM. I don't think on-die cache alone is enough; I certainly wouldn't want to run a 1 GHz Coppermine on a 440BX (if the FSB multiplier even allowed it).

Have you read the article in Tom's hardware, where they did just that and found it to be significantly faster than the i820 system?

In return, 2 other points:

In Intel's own published specmarks, at www.spec.org, the 800 cumine has almost exactly the same performance with PC100/ 100 mhz FSB / BX chipset as it does with the 820/ 133mhz FSB / Rambus memory.

As for the PIII/Althon comparison, the 1ghz Athlon is hampered by 1/3 speed cache. This has nothing to do with Rambus either.

As far as the validity of Tom's overclocked BX, you can make vague references as to how somebody at Intel says it isn't valid all you want, but it's only 33% faster timing, and the BX is 2 years old, isn't it? How much faster are Intel's circuits on the other side of the chipset compared to 2 years ago? Somewhat in excess of 33% faster, it seems.

Cheers, Dan.
